It's a dependent clause.

The "also" applies to "the decision", as opposed to "the initial results".

The sentence is quite the run-on, and it's awkwardly constructed; however, it's grammatically correct.

A less awkward construction would be:

"Citrix's operations review initially resulted in a decision to spin off the GoTo collaboration products business into a new company. In addition, it has also motivated a decision to institute a euphemistic (in the opinion of the editors of CIO.com) 'realignment of resources', which is expected to eliminate approximately 1,000 full time and contract positions in the remaining company."

Here's the actual press release from Citrix, rather than a slashdot summary of a CIO.com article:

Xen is already on the enterprsie radar, http://www.citrix.com/products/xenserver/features/editions.html.

You have to options 1) "bare-metal" hypervisor virutalization 2) "layer-2" virtualization - i.e. VMWare Workstation, Virtual Box, Parellels, etc running within primary OS Option 1 you can use free Citrix XenClient http://blogs.citrix.com/product/xenclient/ The problem is...limited hardware support. This is the primary issue with achieving option 1. Option 2 as long as your PC is powerful enough there is no problem here.

That's what I'm waiting for, one core OS at boot (specialized BIOS?) on top of which I can install several other OS' and switch between them with a keyboard shortcut.

What you're looking for is called XenClient. It's targeted at laptops, but it should work perfectly well on desktops.

It does, unfortunately, require systems with either VT-d (Intel) or an IOMMU (AMD).

I do not agree. The days of an physical desktop in the enterprise with all of your "stuff" on it are going away. The enterprises are moving in the direction of virtual machines and virtual applications. This provides the user with a BYOC (bring your own computer) option and still provide them with a consistent interface and a "computer" to them regardless of where they are connecting to it from, it could be their home laptop running XP, Windows 7, Apple, iPad, or even Linux, their moms desktop, an android device, some thin client on their desk at work. All they need is the receiver software installed on some compatible device which is a simple install and some type of network connectivity (an example here).

It is not a one size fits all, the dust is still settling and there are some issues that are a little less mature like checking out that virtual desktop or virtual applications and using them remotely without network connectivity but it will be solved.

I think this concept will start to break people away from the MS stranglehold where people want the same software products they have at home that they have at work. You will no longer NEED MS office at home or even to run Windows because you want to work from home and be productive. No more Citrix Presentation server where the apps are slightly different the icons are not the same as you "work" computer. No more GoToMyPC or what ever to connect to that physical desktop at your desk that you are familiar with.

People will not need native methods like MS office/Outlook etc on their tablet or phone any more to do work related stuff.
           

The xen.org project has mainly been focusing on server-style virtualization, without desktop graphics (although graphics pass-through is obviously a priority for the Intel engineers).

What you describe really needs not just a single piece of software, but the full configuration and integration with a distribution. If you're not opposed to using software that is partially closed-source but free-as-in-beer, you could try XenClient. It's designed to run on laptops, and specifically tweaked to pass the GPU through to one VM. But there's no reason it couldn't run on a desktop with the right hardware.

I wrote this back in 2001, and it's still relevant!

Running through something like a Citrix Netscaler helps filter out much if your lines aren't overwhelmed.

There are a few other companies that seem to have a solution, but this really looks more like a CDN with enough capacity and some filters to ride out what ever attack could be launched at them.

As a few others have said, XenClient is pretty cool if your hardware is on the (short) compatibility list. My work E6500 is unsupported only due to its Quadro (rather than Intel integrated graphics), so I'm waiting for Nvidia support. I've only had a chance to play with it a little bit on a new E6410 that I had for testing, but it was quite interesting for the little bit of playing I did with it.

Do you want to run a pure virtual environment? Or do you want to boot an OS, and inside that, boot a VM with the other OS? do you have the ability to have a dedicated computer to be the "hypervisor" (so that it can manage the VMs)?

VMware 7 offers great graphical capabilities, altough you should be aware that right now no VM solution offers an 100% seemless graphical experience (altough we are getting there).

Anyways, XenClient might be the thing for you, as it claims to offer full HD graphics usage inside VMs. However, it's in an early stage, and they seem to be marketing it as mostly laptop oriented (if not laptop exclusive).

I have experience with virtualization, so I might help you out :)

Sure,
I have your problem solved right here:
http://www.citrix.com/English/ps2/products/product.asp?contentID=2300325&ntref=prod_top
Basically, it's a bare metal hypervisor for your systems. Fire up an image and you're good to go. Upgrade to new hardware? No problem, you're virtualized. Remote users with laptops? No problem, remote reimage works too.
Yay? :D

"Citrix makes it easy to use enterprise applications, including Windows applications, on your iPhone, Blackberry, Android and Windows mobile devices on-demand."

(full disclosure up front, I'm a Citrix employee)

Either Citrix XenDesktop would work for your scenario.

XenDesktop VDI edition would let you maintain a single OS image .VHD file in your datacenter. You could run it on Citrix XenServer (based on Xen.org hypervisor) for free or swap in VMware ESX/ESXi/vSphere or Microsoft Hyper-V, whatever your preference is.

Stepping up to XenDesktop Enterprise or Platinum Editions would allow you to take that single .VHD image, skip the hypervisor and stream it directly down to each different endpoint device. You would just need to prep the image to ensure it has all the neessary drivers.

XenDesktop Express is a free edition of the product that you could also use for up to 10 endpoint devices using the first delviery method. You would need to clone the .VHD image for each system as the provisioning component that allows single image management isn't available in the free edition.

Incidentally, I noticed somebody point out Citrix XenApp as a possible solution earlier. That product would be better suited to virtualize the applications not the entire desktop. It is included with both XenDesktop Enterprise and Platinum Editions as well.

The "Turn off menu animations" policy does not work as designed. This fix removes the policy interface from the console.

This one was great (it still runs through my mind to this day). Credit to Greg Reese for picking this one up.

Now, this would be the only time I have seen them do this, but it's still funny nevertheless.

From citrix's support site

You can use heartbeat + Xen over 2 boxes to get HA, so long as you have shared storage. There are some notes about how we did Xen live migration on our "perspex box" in my comment here: http://ask.slashdot.org/comments.pl?sid=1171301&cid=27295879 Citrix Xenserver now offers "Live Motion" for free: http://www.citrix.com/English/ps2/products/feature.asp?contentID=1686939

First of all, XenServer 5 has HA.

And does VMware free have it? hahaha no.

VMware standard is required and that will cost you $3624 for a 2 cpu socket license with 1 year of support, without any VirtualCenter license.

What I'm trying to find is whether VMWare plays nice with terminal services/Xenn App server/Presentation server/Citrix Metaframe/whatever they are calling it this year. According to this link, the Citrix people of course optimize for that type of server:

http://community.citrix.com/blogs/citrite/simoncr/2009/02/23/Free%2C+as+in+Virtual+Infrastructure

I have two Citrix servers that I would love to virtualize, but I've always heard nightmares with VMware or anything else. But other than that, I'm a VMware fan.

Yes, or at least they advertise HA as a new feature in XenServer5, but it is not free.

VMware also includes HA, and it is also not free. I'm staring at some VMware sales literature for right now, and I honestly can't tell which of the zillion VMware products offers High Availability, or if HA is offered as a free add-on, or a paid add-on, or what. And they recently increased the license costs by $5-10K for the items on my list.

Citrix is also trying to offer a simpler product line, from the looks of it.

Here's the link: Get it while it's hot.

Why did I read this as Get it while it's hot.? The I, T, R, and the X making an S sound?

Based on the vmware/xen comparison chart, there is no limitation...

Does this article (Presentation Server Client 10.x Introduces a New Method for Printing Documents From the Advanced Universal Print Driver) describe the registry key you're talking about?

In my digging, I also found these which I think might help me. I'd STFW'd all these before but come up empty handed until I reread every Citrix support article I could find:

Intermittent Client Printer Autocreation Failures
Mirrored/Inverted Print Jobs Appear when Printing from Presentation Server 4.0 (I'll have to doublecheck what client version the user had installed - it might be 9.x)
And this monster:
Case Study: Intermittent Client Printer Creation and Deletion Failures

Of course, I'm merely optimistic here, not happy. There's a wide, wide gulf between the two.

Software streaming is nothing new. Altiris, Citrix, and Microsft all offer solutions.

Microsoft's application streaming is the best of the three (in my opinion, from demoing each of them). They acquired it from another company, and the technology was formerly called SoftGrid.

It allows amazing flexibility, because all you really need to do is "sequence" the app, and it creates a file called Feature Block 1, which contains only the portions of the program required for initial launch. The rest of it is streamed on-demand as other parts of the app are accessed, and also in the background at all times.

You deploy apps by associating them with security or distribution groups, and as long as the client machine has the app-v client, you're set.

I've used it to sequence apps like Quake 3, Counter-Strike, and Warcraft 3 for my home network.

First download on this page is a Linux ARM ICA client.

I don't see how this helps. The 'recipient server' will still not be able to keep pace with traffic and a large number of customers will have their access to the service denied. How is this really different than the typical response to a DDOS attack?

Also, it's pretty standard to throw up a load-balancing routing layer between clients and servers, so it's not like this is a new concept.

The idea to make it consistent and a part of the baseline for a phone.

You're right, just like Cisco did for years (thanks to Net6).

In my opinion this article does not present any new facts. It has already been proven for years that server based computing can cut down costs drastically. Terminal server software like the Thinstuff RDP Server for Linux (www.thinstuff.com), Microsoft's terminal services (http://www.microsoft.com/), Citrix (http://www.citrix.com/) and others provide solutions which can never be perfectly solved in a distributed fat-client environment, with distributed updates, security policies for home working laptops,...

"an IT employee .. said part of the problem .. is that the Citrix Application .. just can't handle the load .. we actually use it from inside the network .. and we're running into monumental problems in scaling the Citrix servers"

Technically speaking, how would connecting from 'inside' be any different that outside. it's just packets being moved around.

"Another issue is with the Epic software and its adaptability, according to Deal and the IT employee. They said the software was written in MUMPS (Massachusetts General Hospital Utility Multi-Programming System) -- a health care programming language originally developed in the 1960s"

I recall someone telling me about MUMPS. You ran it off 5 ¼ floppies and accessed the data through direct access to a b-tree.

"Using Citrix is something that defies common sense. It would be like trying to use a dial up modem for thousands of users. It's just not going to work, and it's not something anyone would tell you a dial-up modem should work for"

What if anything is Citrix designed for but for large scale remote access.

Although the article specifically states that this is a windows solution, I think it's worth noting that sunray works exactly like this. You put the smartcard, your previous desktop session is instantly restored, you do what you want to do, you pull out the card. Your desktop session is preserved and is terminal independent.

As for the lack of windows applications, it is actually possible to do it even on sunrays , although admitedly it is not particularly suitable for the small scale that the article submitter implies.

Anyway, you might take a look at those two links, and if you must absolutely use PCs (sunrays are more suitable for the job the article is outlining), take a look at citrix also. I don't know whether they do smartcards though.

Citrix provides their ICA for linux.

http://www.citrix.com/site/SS/downloads/details.as p?dID=2755&downloadID=3323

I used it for a year before I dumped citrix for native 2003 terminal services. Now I just use the TSC client that's built into Ubuntu.

The really nice thing about citrix clients is that you do not even have to use windows on the client side. You just have to point your browser at the right citrix helper binary...I set it up for my wife (who works for a large BC hospital chain) now we are a windows free environment... at least at home. She tells me that the linux client setup on Slackware runs faster than her newer XP pc at work with 512meg of ram! The citrix client runs smoothly on Xwindows with a minimal X gui like Windowmaker or Xface and really smokes with 128 meg of ram and a P111 450! It runs a little slower however on KDE but that is the price you pay. If I had gobs of ram like her work pc I am sure it would cook along fine even with a big gui like kde.

Someone better tell them.

This or even thison one of the following phones can do that kind of thing. SSH over EDGE, GPRS, or 802.11(9300i/9500) - even with the cameraless models. Full keyboard on those three and not terribly large, and looks like an older phone when folded. If you can live with the camera, go with the 9500 and a large media card, otherwise the 9300i is the best bet.

The only real thing missing from these is the SIP client that Nokia has in testing for these phones that they cant seem to release. After that, you can have all the calls you want without a conventional endpoint as well as a remote client. Other than that they might not want the Series 80 to compete with the E series, there really doesnt seem to be much of a reason to hold it back. Even then, that reason doesnt hold terribly well.

Unfortunately, the cost of migrating the users that will eventually use this system, between training and lost time on the job and numbers (25 is merely a pilot) would be prohibitively expensive. In addition, there will be included costs for porting the software that is used by all of the users, as well as the software that does not exist on Linux or Unix.

When you total up all those applications (MS Office/Outlook as OpenOffice will not do for our admins, in house software, etc) it is uncertain whether you are gaining any benefits by having a unix infrastructure underneath it or not. Certainly, if the unix option can fulfill our specifications (we are currently considering sunrays) we are certainly willing to consider it. However, smooth integration between unix and windows, even with citrix, is not nearly as smooth as it looked. For instance, there are many limitations for the non-windows versions of the ICA Clients. You may do a feature comparison yourself at:
http://download2.citrix.com/files/client_feature.x ls
or google for "citrix ica client matrix". For us, a big one to get it into these locations is USB PDA sync, which does not except for windows and linux, and multimedia acceleration, which only works on windows. Smart card support for the ICA client also only works on windows

We already have experience with much less capable boxes holding 25 user with little issue to speak of. Our current estimate on the latest Dell servers specced out for our situation would be about 50 users per machine.

We have already looked at crashing servers and are planning on using clusters of machines. Windows does have failover clustering. I am not an expert on Citrix, but I believe they have some fault tolerance as well.

I should note that outside of regularly scheduled patches, all of our terminal servers have experienced very little downtime in the last two years. I'm talking on the order of a day total per machine. A well maintained windows machine can be an extremely reliable thing. The knowledge of the admin behind it (not me, in this case, I'm much more unix oriented, having been a unix admin for a large organization for 7 years) usually improves the reliability.

Citrix bought a company called Net6 a couple of years ago. Net6 made an SSL VPN "appliance", which runs a hardened Linux OS. Citrix rebranding it as the "Citrix Access Gateway", or CAG.

The 1st iteration was not so good because they rushed the rebranding and integration stuff. The 2nd and 3rd iterations were OK.

The latest revision is quite good. It supports around 2000 concurrent users, has easy to use yet powerful access controls and integrates nicely with Citrix's Presentation Server 4 product.

The cost is pretty good: the box is $2500 and licenses retail for around $100/concurrent user. If you have 100 users and your highest expected concurrent remote access count is 25, your cost would be $2500 + 25 x 100 = $5,000. If you buy 2 boxes (they have a built-in failover mechanism for redundancy), the cost would be $7500.

I work for a major healthcare provider and we're replacing Cisco VPN concentrators with the CAG. We bought 4 CAGs and are using Citrix's Advanced Access Control (AAC) product to integrate the CAGs with our internal portals (AAC makes the cost go up pretty high, though). We have around 40,000 users and our max concurrent remote users is currently around 4,000.
